Wood humidity sensor DSE LoRaWAN

LoRaWAN wood moisture sensor for structural monitoring

The Wood humidity sensor DSE LoRaWAN is a DS Energy wireless sensor designed for long-term monitoring of moisture content in timber structures. The sensor measures the electrical resistance of the wood between two electrodes and converts the result into wood moisture content, while LoRaWAN communication enables remote data collection.

The resistance method is based on the relationship between moisture and electrical conductivity in wood: increasing moisture content reduces the electrical resistance. The measurement method provides an accuracy of approximately ±1.0% for wood moisture contents from 7% up to the fibre saturation point, with the specified accuracy applying when the wood temperature is between 10 and 30 °C. :contentReference[oaicite:0]{index=0}

Wood moisture, temperature and humidity monitoring

The sensor is installed directly on the timber using two measurement screws with a predefined spacing of 28 mm. For best measurement consistency, the electrodes should be positioned perpendicular to the grain. For glulam structures, both electrodes should be installed in the same lamella. :contentReference[oaicite:1]{index=1}

The device supports Generic, Pine and Spruce wood configurations. Measurement data transmitted in the LoRaWAN uplink includes ambient temperature, ambient relative humidity, battery level, wood moisture and the selected wood type. :contentReference[oaicite:2]{index=2}

Ambient temperature and humidity sensing is individually calibrated by the sensor manufacturer. The documented typical accuracy is ±0.2 °C for temperature and ±2% RH for relative humidity under specified conditions. :contentReference[oaicite:3]{index=3}

The sensor communicates through a compatible LoRaWAN gateway for remote monitoring and data collection.

Installation and connection

Mount the sensor at the required measurement point using the supplied measurement screws. The electrodes should be installed 28 mm apart and preferably perpendicular to the wood grain. Once mounted, activate the sensor using the push button and verify correct measurement using the status LED. Register the sensor on the LoRaWAN network for remote data collection. :contentReference[oaicite:4]{index=4}
